Power commander 5 ignition timing on sportsman 1000

Hi guys, first post on the forum. I’ve kept up and read alot on here. There is some great information here. Anyways I recently bought a 15 sportsman 1000 LE to add to the 850. I read all the post about the hot exhaust and had it dyno ed to see what the baseline is. It made 58 hp but the fuel is a flat 14.0 all over. I thought it would richen up at wot but it still the same. My question is I’m probably going to put a power commander 5 on and I’m just wondering what kind of gains anyone has seen with advancing the timing? I’m Going to tune for around 13 afr. And then go for the timing. It just seems like there’s a lot on the table for this engine. Thanks for your advice.
